[Previous technology] The conventional ratchet screwdriver is a common hand tool, which can be connected to a tool head and used to fix or unscrew a fastener (such as a hex bolt). The actuating part of a conventional ratchet screwdriver uses gears to cooperate with each other in a planar direction and can be rotated in a fixed direction. It cannot be used in both directions, which results in restrictions on use. At the same time, it cooperates with the gear's horizontal setting to make the actuating part larger. In order to improve the shortcomings of the above mentioned ratchet screwdriver, there is another ratchet screwdriver on the market. The direction of the ratchet screwdriver can be changed by pulling an adjustment button, and it can be operated in both directions. However, this kind of ratchet driver still has the disadvantage of a larger or longer actuating part. Therefore, when the ratchet driver is applied in a narrow space, the larger actuating part is often difficult to extend into the space, or even after extending into the space. It is not easy to exert force. Furthermore, the ratchet screwdriver with the adjustment button uses an iron piece to pull the inner part of the adjustment button to change the action direction of the ratchet screwdriver. Such an adjustment method of changing the action direction is prone to damage due to insufficient torque of the iron piece. Therefore, the conventional ratchet driver still has many inconveniences in use, and further improvement is needed. [New content] In view of the disadvantages of conventional ratchet screwdrivers, the author has improved the design, mainly to provide a ratchet screwdriver with a simple structure that can provide small size and convenient use as its main creative purpose. M246112 In order to achieve the purpose of the creation, the technical means used in this creation is to provide a ratchet screwdriver, which has a body part and an action part placed on the body ^, and the 4 body is provided with a -grip A support rod is connected to the grip, and the support rod is connected with a non-®-shaped sleeve at the end different from the connection grip. The sleeve is connected at the end different from the connecting pole. There is a head with a ring-shaped fixing groove, and a ring-shaped fixing groove is provided between the fitting portion and the head: the actuating portion is provided with a set of springs provided in the fitting portion, and the sleeve is fixed to the fitting in a non-rotating manner. The opposite end of the tooth sleeve is against the jelly tooth sleeve. The tooth sleeve is formed on both end faces with tooth faces with opposite tooth surface directions. A C-shaped ring that is respectively snapped and received in the annular fixing groove is located in the tooth sleeve. The c-shaped ring between the fitting portion and the head is elastically clamped on the inner edge of the corresponding end of the tooth sleeve; and a tool joint that is sleeved on the head in a rotatable form, and the tool joint is formed on the inner wall with a corresponding The receiving groove of the C-shaped ring provided on the head faces the toothed sleeve. The end surface is provided with a tooth-shaped protrusion capable of feeding the tooth portion provided in the tooth sleeve. By the above-mentioned technical means, the ratchet screwdriver of this creation can achieve the following effects: 1. Since the tool joint and the tooth sleeve cooperate with each other by the tooth portion and the tooth-shaped protrusions, and the engagement action of the action portion is radially arranged, Therefore, the smaller moving part of this creation can be used in a smaller space. 2 · The ratchet screwdriver of this creation is composed of the above-mentioned several components, and has a relatively simple structure. When the components of this creation are worn, the components can be easily replaced. 3. Since the tooth sleeve and the tool joint of the actuating part of this creation are affixed with each other by the tooth part M246112 and the tooth-like protrusions, the area of the actuating spray is large, so it can provide a large torque. [Embodiment] Please refer to the first and second figures, the ratchet screwdriver system of this creation includes a body part (20) and a set of action part (ι〇) (20) It has-a grip (21), the grip (2 1)-end connection-support rod (22), the support rod (22) is different from the end of the connection grip (2 1) and is provided with an abutment seat (2 3) The abutment seat (23) is pivoted with the swing rod (22). The abutment seat (23) is provided with a support rod (22) at the end of which is provided with a fitting portion (24). The fitting P (2 4) The outer periphery is hexagonal, and is different from the frame joint (2 3 is additionally provided-the head (25). The head (25) is cylindrical, and a ring is formed on the outer periphery. Type fixed groove (251), and another god: 2 5 2) is arranged between the head sleeve (2 5) and the Xiao sleeve part (2 4). U 疋 槽 （° ハ 作 动 ° 卩 (1 〇) has a An elastic member, preferably the elastic member 4 is a spring (1 4), and the spring (i 4) is sleeved on the abutment seat (23) of the body (f 0). The tooth sleeve (" ):, In a hexagonal shape that can cooperate with the fitting part (2 4), and fit in the fitting part of = (2〇) 24) i (> The tooth sleeve (13) has a ^ i ^ surface, and a tooth portion (1 3 1) with a tooth surface is formed on one end surface) A tooth portion (132) with a tooth surface facing the opposite direction is formed on an end surface The inner wall of each tooth (131, 132) connected to the tooth sleeve (13) is shaped ^ M246112 has several inclined surfaces (133). The two c-rings (120, 121) are respectively fixed in the ring-shaped fixing grooves (2 5 1,2 5 2) to provide a flexible and abutting effect, and then a tool joint (work 1) is set on the head (25) of the body (20). The tool joint (1 1) One end is provided with a fixing hole (1 1 1) through which various tool heads (30) can be fixed, and the other end is a through hole (112) through which a body (20) can be inserted. (Please refer to the second figure for cooperation), the end surface with the through hole (1 12) is provided with a tooth-shaped protrusion (113), and at the same time, the c-shaped ring (12) in the ring-shaped fixing groove (251) is fitted. 〇), the tool joint (1 1) has a receiving groove (1 1 4) on the inner wall of the near-tooth sleeve (1 3). 〇 As shown in the second figure, when using the ratchet driver, the tool joint (1 1) can be accommodated by the C-ring (12) and the inner wall of the tool joint (1 1) The slots (1 1 4) are locked with each other, so that the tool joint (i) can be pressed against the head (25). When the tool joint (11) is to be pulled out, the C-shape is formed by the inner wall of the tool joint (1). The ring (1 20) is pushed toward the annular fixing groove (251), so that the c-shaped ring (12) is retracted from the latch receiving groove (114), so that the tool joint (11) can be pulled out. Force the tooth sleeve (1 3) to pass through two sets of c-shaped rings (120, 121) set in the ring-shaped fixing grooves (251, 252), so that the tooth sleeve (1 3) can be fitted on the sleeve When the joint (24), the toothed sleeve (1 3) can also bear against the inner wall of the toothed sleeve (13) by the c-shaped ring (1 2 丄) at this time to prevent the toothed sleeve (13) from leaving the sleeve. (24) 'At this time, the inclined surface of the inner wall of the sleeve (13) (job 3 3) just touches the c M246112 ring (121), and the inclined surface (133) is also provided-it is easy to pull out the toothed sleeve (1 3). the way. Please refer to the third and fourth figures. When using, the tool head (30) to be used can be set in the fixing hole (11) of the tool joint (11). Since the tooth portions of the two end faces of the toothed sleeve (1 3) (3 丄, 3 2) ′ have tooth surfaces facing different directions, because of Λ, when the toothed sleeve (13) is pulled out, the transformation is different. When the teeth of the end face (3 workers,) and the tooth-shaped protrusions (1 1 3) of the tool joint (1 1) are combined, the ratchet screwdriver can be used in different directions of movement ^ At the same time when using the ratchet screwdriver of this creation Due to the different degree of force, the spring (丄 4) can provide the ability of the tooth sleeve (1 3) to reset. Because the ratchet screwdriver of this creation has a tooth-shaped protrusion (1 1 3) and a tooth portion (] L 3 1, worker 3 2) in a radial engagement with each other between the tool joint (1 and the tooth sleeve (1 3)). The ratchet driver can be used in a smaller volume and can be used in a narrow space. In addition, since the tooth sleeve (1 3) and the tool joint (1 1) are fused with each other by the end faces, the operation The surface is large, so it can provide a large torque, and it is not easy to be damaged. Furthermore, because the creative component is simple, the production cost can be reduced, and the grip (2 1) and the sleeve (2 3) are pivoted.
